Three-row roller slewing ring


  • In order to transmit the loads previously defined, it is necessary to realize an adequate mechanical fastening of the bearing on the associated frames, thus forming rigid connection of the ring and its supports.While several fastening methods are feasible, the most efficient one remains the use of screws and nuts.Welding operations are absolutely prohibited.The slewing ring proper functioning and the application safety are dependent on the correct bolting definition and fastening method during installation, complying with our workmanship.

  • Slewing ring bearings usually have diameters ranging from 0.2 to 10 meters. They are composed of mounting holes, inner or outer gear rings, lubricating oil holes and sealing devices. The mounting holes are divided into through holes and threaded holes. It is different for various industries. The slewing bearing has a variety of structural types to adapt to the use requirements, and can meet the needs of the main machine function with different manufacturing precision levels, so the slewing bearing is an indispensable machine component on the slewing device of medium and large construction machinery. part. It occupies a pivotal position in the machinery industry, construction industry, coal industry and shipbuilding industry.
